| Subject: | Plane Power and Lycoming Pulley Alignment Issue |
Putting together comments from several people, it appears that
Van=99s and Lycoming made this change about two years ago. The
comment that I got was Van=99s was that most of their engines are
going to Brazil and they use a/c. Somebody made an executive decision
and didn=99t inform Plane Power. In talking to them, they are
very anxious to solve this problem, but appeared to be caught off guard.
I guess folks are modifying brackets and spacers themselves.

That definitely is not right. I've never seen that problem before. Could
the alternator bracket is really to only variable that I can think of.
Can you get some measurements off that and have people on the list
compare?
As Deems said, I have only seen the dual belt pulley used w A/C,
although in the most recent installation I have seen the compressor was
on the left side and the alternator stayed on the right. That was an RDD
installation of the Flightline A/C system.
I think somehow your alternator bracket is wrong.

I installed a dual-pulley ring gear with a standard Plane Power

Bob,
Seems to me that the easiest fix would be to machine the difference
from the back of the alternator pulley to bring the belt into alignment.
Whether there is a spacer, or if the pulley has a one piece boss, should
be easier and cheaper than hunting down a new flywheel..
Take a look, if you need it machined and don=99t have a quick
resource locally , take a measurement and send it this way.
(one other thought is that you may be able to flip the alt pulley if it
has a boss and place an appropriate new spacer under it to correct your
issues.
just make sure there is enough thread on the alt shaft for the nut)
(assuming it has a keyway rather than a taper )

Machining the pulley may be an option after engineering approval from PP. I would
not want to weaken the pulley too much.
While waiting for all of this to get hashed out I am going to pull the rear spacer
and machine it down approx .120 then add two 7/16" AN washers to front spacer.
Also I am going to straighten tension arm.
Once PP comes up with a fix I can swap out the parts.

| Subject: | Re: Plane Power and Lycoming Pulley Alignment Issue |
So I have had conversations with Vans, Lycoming, and Plane Power.
Vans passed the buck even though they made the change to go with the dual pulley
flywheel about two years ago from what I can tell.
In talking with Lycoming, they were unaware of the issue with the Plane Power alternator
not aligning with the dual pulley flywheel. It has been escalated to
their engineering department and I'm awaiting a response from them at the moment.
The mentioned that 2/3's of the YIO-540s sold to Vans are going to Brazil.
Plane Power states that there alternator will not align with the dual pulley flywheel
from Lycoming. They are anxious to resolve this issue. Both Vans and
Lycoming are big customers of theirs. They were going to call both Vans and
Lycoming today to discuss the details. (Jesse they were curious as to how you
got your's to align without modification)
At the moment, there appears to be two solutions.
1. Van's must indicate an option to choose whether or not you need a single or
dual pulley flywheel.
2. Plane Power must fabricate a new bracket for the dual pulley flywheel.
Both Lycoming and Plan Power seemed frustrated since Van's only wants to order
a single sku from them. It appears that Van's made this change, but didn't coordinate
with both company's engineering departments to ensure that everything
worked.
At this point in time, I'm awaiting responses from all three vendors to see how
the choose to resolve this issue. I'll keep everyone posted.

I had a dual pulley, but couldn't use it with the Lightspeed ignition circuit board,
it would not fit under the flywheel. So may be something to consider if
you are going the Lightspeed route..... Unless the newer flywheels are bigger??

John at Flightline here. The best PMA part for a dual groove pulley is the
LW-10184. It retains the original groove from the Lyco 540 10" pulley, as
well as adds the one we need for ac. I can't speak to the alternator
alignment as there are so many, but I haven't heard any complaints about the
belt alignment of the Plane Power or the B&C until this thread. We have had
numerous instances where people have thought that they were being sold a
dual groove pulley with their engine only to find out that it was a trim
groove, not a belt groove to shave weight from the pulley. You might be
looking at such a situation here also. The true 2 groove pulleys are
exactly the same at the bottom of the groove. The single with the shaved
groove is different and typically places the belt right up against the body
of the ring gear support.
The fore mentioned 2 groove (LW-10184) is ideal for lightspeed acceptance
also.

Mine is LW-12227. The fwd groove is a vee shape and the rear is a u shape. Maybe
just for reducing weight but the rear u shaped groove is approx .120" aft of
PP alt pulley groove.

O.D. of my pulley is approx 9" and I had to purchase a Gates 7328 belt to fit.

Sounds like a bracket adjustment/reconfig is in order then. Pretty sure
that the 12227 is only a single groove. I have a 12226 here and it is
definitely a single posing as a 2 groove. I'd be interested in knowing if
the B&C is better aligned with that ring gear, or if the change in the drive
pulley is what is causing the mis-alignments. There used to be no
difference in at least these two alternator offsets.

Mine is LW-12227. The fwd groove is a vee shape and the rear is a u shape.
Maybe just for reducing weight but the rear u shaped groove is approx .120"
aft of PP alt pulley groove.

Why not just machine a new set of spacers? Keep the existing bracket.
The alternator just need to move aft about a 1/4 inch. The bracket would
allow that.

Machine the spacers NOT the pulley(s).

Nope, the LW-12227 is as Wayne described. I have the same one.
I only know of one data point at the moment that has the same version of
engine. He mentioned he didn't have an alignment issue with his B&C.

Mine is LW-12227. The fwd groove is a vee shape and the rear is a u shape.
Maybe just for reducing weight but the rear u shaped groove is approx .120"
aft of PP alt pulley groove.

It wouldn't make much sense that if the big difference is the large pulley/ring
gear, and by changing that part, you would only screw up one type of alternator.
If the plane power and B&C had the belt in the same alignment plane before,
then changing only the large pulley type should wreck the alignment of both
alternators the same, unless there are some very strange other engine case factors
at work.
My bet is that there is a larger variation in large pulleys more than just the
single and the double.

I'm almost glad i'm not alone! :)
Same thing happened to me. I ordered my engine from Vans with the dual groove ring
gear because of my A/C compressor.
Talked to PlanePower at OSH, and they told me to just have a machinist grind down
from the spacer on one end, and use a washer on the other.
Haven't done that yet, but it would be awesome if PlanePower provided the correct
spacer.
There may be another problem though. The dual groove ring gear i got from Lycoming
had two different types of groves. One V shape and the other a V shape with
a square bottom. Bill at Airflow Systems machined them to the correct shape
so I can use the standard belts.
The other smaller problem is that the spacers are glued together onto the alternator,
which may not be so much fun to remove.
If anyone finds a solution to this, please post it on here.
Lenny
